Abstract

The node has a star coupler (46) associated with a combiner (30) i.e. periodic multiplexer, of wavelength channels. Two outputs (50, 53) of the coupler are connected to optical insertion paths (52, 55) associated to the combiner. Third output (132) of the coupler is connected to an extraction module (127) of optical packets. Inputs (102, 109) of the coupler are connected to packet outputs of wavelength channel separators by optical extraction paths e.g. optical fibers. Each separator separates the wavelength channels carrying data packets at a node output on which the combiner is arranged.
